intel/compiler: relax brw_eu_validate for byte raw movs

Browse Source 
When the destination is a BYTE type allow raw movs
even if the stride is not exact multiple of destination
type and exec type, execution type is Word and its size is 2.

This restriction was only allowing stride==2 destinations
for 8-bit types.
